Here's an important article from William Cooper:
http://www.hourofthetime.com/majestyt.htm

maybe it's on this site somewhere else, if not it should be. His article incorporates many observations of conspiracy theory from ufo's to communism, masons, Art Bell, NASA, FBI, terrorism, Golitsyn etc. Perhaps Cooper is mistaken about the physical landing of the Apollo missions, but his thesis on UFOs seems sound. He knew that much of the UFO community was CIA disinfo, although he didn't make the connection between high level gov't "admission" of the existence of ETs and future mind control agendas.
